As I quoted tweet in BCHL thread (yesterday), players can have NO physical contact and must maintain 3m distancing. So these "drills" and practices you mention would essentially be skating only. No faceoffs, battle drills, shinny.
Sharks are looking to play/practice in a county other than home due to recent restrictions. And now the governor has put even more restrictions (back) in place.
Makes you wonder whether the NHL will be forced to play in a bubble again at least to start the season.
The rules may be limiting in BC but they have been put in place to avoid the skyrocketing infection rates in the Canadian prairies. At this point I don't see how the NHL can possibly avoid team outbreaks in Calgary, Edmonton, and Winnipeg if they allow players to live in the community.
Of course all throughout North America the problem exists - infection rates are highest in the US Midwest. In my opinion, the hurdles of starting a new season will not likely come down to escrow / deferred salary. Rick Westhead of TSN
laid out how weak a case the NHL has yesterday.
But instead are the players willing to go back into a bubble? Will they be allowed to bring their families with them? It may be the case that the players would prefer to delay the start of the season to minimize the time spent in "lockup."
So instead using the (toothless) threat of cancelling the season, the NHL may now be tacking in the other direction: the players will play under the NHL's conditions. Want to negotiate on those conditions? Then things like escrow / deferred salary are back on the table.
